(CNN) Roger Federer has announced he will not play tennis again this year after undergoing further surgery on his right knee. The 20-time grand slam champion had been recovering from surgery he underwent in February but suffered a setback in his pursuit of fitness a few weeks ago. "I had to have an additional quick arthroscopic procedure on my right knee," he wrote on Twitter Wednesday. "Now, much like I did leading up to the 2017 season, I plan to take the necessary time to be 100% ready to play at my highest level. "I will be missing my fans and the tour dearly but I will look forward to seeing everyone back on tour at the start of the 2021 season."
